BUTTON-MACHINE.

SPECIFICATION forming part of Letters Patent No. 396,427, dated January22, 1889.

Appncaaon med April 5, 1888. sei-aina. 289,675. (No model.)

To all whom it may concern:

Be it known that I, CARL AUGUST PFEN- NING, a subject of the GermanEmperor, residing at Barmen Rittershausen, in Rhenish Prussia, Germany,have invented a new and useful Apparatusfor the Manufacture of Buttons,of which the following is a full, true, and exact description, referencebeing-had to the accompanying drawin This machine consists of' mechanismfor forming buttons, especially he'mispherical in shape.

Iteonsists, essentially, oit two parts-thebase for receiving the moldand covering material, called the button upper part, and the cover forreceiving the shank or button lower part.

My invention will be readily understood from the accompanying drawings,in which- Figure llrepresents a sectional elevation 5 Fig. 2, a top viewof the cover; Fig. 3, a detail of the button-raising mechanism, and Fig.it mechanism for altering the size of the stamp for differentfshapedbuttons.

B represents a cap or cover, and E the base fitting the same. The cap Bmay be pivoted upon the lower part or arranged in any other way so as toassume the position shown in Fig. 'l for making'the button when it is tobe locked upon the base. The base itself contains a cylindrical core,C', driven upward through the cylinder E by suitable mechanism-forinstance, an eccentric upon a shaft. The cap B sustains the part i2,which is'provided with a peculiarshaped slot, r r2. Through the centerot' the part G2 traverses the plunger or stamp S, driven downward by aspring, s, as shown. The lower part of the cover B, which is somewhatexpanded, contains the disk-shaped guide-plate p, which is verticallyadjustable in this space, and the springs bears against the part G2 andthe guide or part p. \Vithin the movable guide or part p is screwed thestamp S', which traverses the ifolding-die B, as shown. The part B isheld in the part B by the pronged wire d, as clearly shown in Figs. land 2. On the withdrawal of this wire a different-shaped part may besubstituted, and a corresponding difference may be made by substitutinga new plunger, C', or a plunger with a variable head to correspond todifferent-shaped buttons.

The part B has a bending-flange, g, as shown. Through the center of thestamp S and the plunger S passes the wire hook 7L. The end of this hookmay be a hook, as shown, or, it' a clotlrshank button is used, a pointto catch in that cloth shank. The upper end ot the stamp S is providedwith atransverse slot, is, as shown, and the wire itself is lifted bythe button h2, having a stem, h3, adapted to drop into the slot at oneposition ot' its revolution, and otherwise to be sustained upon the edgeby pin s. A pin, s', supportedl in the stem h3, serves to rotate thestem h3 into the position when it will drop in the slot. In Fig. l thepin rests upon the top of S, while in Fig. 3 it has dropped within theslot. This revolution is accomplished by the engagement of the pin supon the xed pin f2, fixed in the part G2, as shown. The part S isprovided with slots p2, with which a key,U, engages, so

that different parts S can be screwed into the stem S.

The operation of my machine can now be readily understood. The mold andbutton are dropped upon the core, which is at first depressed. Byturning thehandle h2 the hook 7L is dropped and the shank hooked uponit, the cover being raised. This position is shown in Fig. 3. The buttonh2 is then raised and the pin revolved into the position shown in Fig.2, thereby holdin g up the shank until it is again dropped by therevolution of the stem i3. The machine is then closed upon the mold andsurrounding material. The piston C is then raised to the height shown inFig. l, and the handle R being turned to the position shown in Fig. lthe pin s strikes upon the fixed pinf2 and drops the wire hook 71, intothe position shown in that figure. The continued turning of the handle Rafter the button lower part has been dropped into the button upper partand pressed therein by the stamp S raises the stamp S out of the way,and the continued upward motion of the core C bends in, by reason ot'the bevel g, the metal mold and cloth forming the button upper partaround and embracing the button lower parti tUpon raising the cover B,the hook h being in its lower position, the button islreadily detached.

NV hat I claim as my invention, and desire to secure by Letters Patent,is-

l. In a button-forming machine, a cylinder IOO Within which the buttonis formed, a core for raising,` the button therein, a stamp having itsaxis coincident with the core, and a hook for sustaining` the buttonpassing through said stamp, substantially as described.

2. In a button-forming' machine, a movable guide and a stamp, S,supported and centralized thereby `and detachably connected thereto, incombination with the spring;I 3, actuating said guide, and the handleR', travelingl in the slot 0", fo'r elevating the guide and stamp,substantially as described.

3. The combination, in a lnlttom-forming machine, of the cap B, thebutton-forming part B', provided with bevel y, and the stamp S',depressed by sprin s and raised by handle R', traveling' in the slot r',lsnbstanti ally as described.

4. The combination, in a Mitten-'forming machine, of a stamp, S', and acentral longitudinallyanovable button-holding' wire, h', substantiallyas described.

5. The combination, in a` button-forming machine, of the stamp S,provided at its upper end with a slot, a central button-supporting wiretraversing' the stamp, and an arm at or near the upper end of saidsupporting-wire, whereby the latter may be sustained from the top of thestamp or be permitted to drop into the slot therein, substantially asand for the purpose described.

In. testimony whereof I have signed my name to this specification in thepresence of two subseribingl witnesses.
